Abstract
(EN) The present invention provides a vinyl chloride resin plasticizer having a superior balance in terms of non-migration properties, anti-fogging properties, flexibility, heat-resistance, and cold-resistance. Specifically, the present invention pertains to a vinyl chloride resin plasticizer constituted of a polyester having, as the reaction feedstock, a glycol having 2 to 18 carbon atoms, an aliphatic dicarboxylic acid having 4 to 14 carbon atoms, and a monoalcohol having 4 to 18 carbon atoms and/or a monocarboxylic acid having 2 to 21 carbon atoms, wherein the polyester has a number average molecular weight in the range of 500 to 6,000, and the proportion, in terms of area, of components having a molecular weight of 600 or less is within the range of 0.5 to 3.0 mass% as measured via gel permeation chromatography.
(FR) La présente invention concerne un plastifiant de résine de chlorure de vinyle présentant un équilibre supérieur en termes de propriétés de non-migration, de propriétés antibuée, de flexibilité, de résistance à la chaleur et de résistance au froid. En particulier, la présente invention se réfère à un plastifiant de résine de chlorure de vinyle constitué d'un polyester comportant, en tant que produits de départ de réaction, un glycol doté de 2 à 18 atomes de carbone, un acide dicarboxylique aliphatique doté de 4 à 14 atomes de carbone et un monoalcool doté de 4 à 18 atomes de carbone et/ou un acide monocarboxylique doté de 2 à 21 atomes de carbone, le polyester présentant un poids moléculaire moyen en nombre compris entre 500 et 6000, et la proportion, en termes de surface, de composants dont le poids moléculaire est inférieur ou égal à 600 est comprise entre 0,5 et 3,0 % en masse, mesurée par chromatographie par perméation de gel.
(JA) 非移行性、耐フォギング性、柔軟性、耐熱性及び耐寒性のバランスに優れる塩化ビニル樹脂用可塑剤を提供する。具体的には、炭素原子数2~18のグリコールと、炭素原子数4~14の脂肪族ジカルボン酸と、炭素原子数4~18のモノアルコール及び/又は炭素原子数2~21のモノカルボン酸とを反応原料とするポリエステルである塩化ビニル樹脂用可塑剤であって、前記ポリエステルは、数平均分子量が500~6,000の範囲であり、分子量600以下の成分が、ゲル浸透クロマトグラフィー測定における面積比率で0.5~3.0質量%の範囲である塩化ビニル樹脂用可塑剤。
